It’s not a fight that should be happening. Merab was #1 contender after dominating Yan, before Aljo even lost the belt, Dana let O’Malley duck him out of spite for Merab not fighting Aljo, and instead makes him fight Cejudo for no reason, weeks before this fight.
Sean and Merab could’ve fought on this event, that means O’Malley blatantly ducked him to take a more winnable fight, so as far as I’m concerned O’Malley is no longer undisputed champ, this is an interim title fight until the winner faces Merab for unification.
